"How did you do that?!"

"How the HELL did you do that?!"

– Simon Cowell

"I can't wait to watch this back on TV! To figure out the t-shirt!"

"I don't know how you do it. It doesn't matter. But what I do know is that you are brilliant. And your stage presence and the way you conduct yourselves throughout your act, the way you draw us all in, is hypnotising and I think you guys are brilliant. Really excited about that and that was just amazing. Gobsmacked."

– Alesha Dixon

"You could literally cut the atmosphere with a knife in here. You are so engaging I can't take my eyes off you and I don't know how you did it. Amazing."

– Amanda Holden

"How the bloody hell did you do that. I mean seriously, I have no idea what just happened there. But that was honestly incredible."

– Simon Cowell

"You are one of the most original acts we've had on the show this series. Your presentation is superb. You engage the whole audience - we can't take our eyes off of you and I just think you're fantastic. So many people have been talking about DNA"

– Alesha Dixon

"You are just a fascinating couple of blokes and it's very eerie and very spooky and I have no idea about how technical it was. Like the other guys said you have great showmanship and I just can't take my eyes off of you."

– Amanda Holden

"What you do honestly is incredible. I've got to know you, you're really, really nice guys you deserve this break."
